Iruka no Jikotsu

Overview

Go ahead, say "please"— College student Asami is sex friends with a man who is the embodiment of having no desires. Said friend — Chiaki — was uninterested in anything, to the point he would even skip meals just because it's a hassle. And yet, for some reason, he has sex with Asami. Seeing Chiaki like that, Asami wanted to find something that "strikes a chord with his desires". However, one day, after finding out about Asami's childhood friend, Takara, Chiaki seems to take an interest in him... This is a story of a love triangle between a man with no desires, a man who wished to bring out said desires — and a childhood friend harboring complicated feelings.
